AGIOS GEORGIOS CASTLE
The medieval castle of Agios Georgios is situated near the village of Peratata, on a 320 m. high hill. The castle was built in the 13th century to fortify the island's old capital which was housed here until 1757 AD. The castle owes its name to the large church of Agios Georgios, which is situated in the region and is celebrated glamorously. The castle, along with the island, fell in succession into the hands of the Byzantines, the Franks, the Turks and
the Venetians. On 24 December 1500, after a persistent battle with the Venetians, the Spanish and the people of Kefalonia, the castle was liberated from the Turks.
The severe damage to the buildings led to a restoration supervised by the mechanic Tsimaras, which lasted for four years. Until the earthquake in 1636, the castle thrived and housed storage rooms, a hospital, barracks, private residencies and a prison in which the more liberal people of Kefalonia were kept, whom the current conquerors considered dangerous. The Castle's entire surface area is 16,000 square metres, and the walls are 600 m. long and 1,015 m. high. The three ramparts face Argostoli, the East and Peratata, respectively. The Castle also includes loopholes, observatories and cannon positions. Inside the Castle, one can admire the tower called "Old Fortress", as well as part of the walls, underground arches, the throne of the Venetian Lord and a catholic church, where the nobles of Kefalonia were buried.  
   

AGIOS GERASIMOS MONASTERY
Agios Gerasimos is the patron saint of the island. On its feast day, the monastery is swarming with pilgrims. According to tradition, he was born in Trikala of Korinthia and was a member of the famous Notaras family. He became a monk and spent twelve years in the Holy Land and five years in Zakynthos. He came to Kefalonia in 1560 and stayed in the cave of the same name, south of Argostoli.
 Later, he founded the monastery and took residence there until his death on 15 August, 1579. Two years later, on 20 October, 1581, his relics were placed inside the monastery. He was canonized in 1622. At the courtyard, there is a big plane tree and a well, which is said to have been dug by the saint himself. Inside, there is a trap-door where he is said to have spent the greater part of his life. On the 15th of August and the 20th of October, big festivals and processions take place. Many miracles are connected to the saint's relics and icon.

Drogorati cave stands a few kilometres outside the town of Sami. It is 45 metres in width, 21 metres in depth, and 9 metres in length. It consists of two parts. The upper part has collapsed and only huge stalactites of different colours remain. The second part is the cave proper (65 x 45 m), which is accessible to tourists and houses cultural events.
It has extraordinary acoustics, thus its name: "Hall of Apotheosis". The cave can accommodate about 500 viewers. The regulated lighting in combination with the multi-coloured stalactites creates a picture of unique beauty.
   

IAKOVATIOS LIBRARY

KARAVOMILOS
The area of Karavomilos is situated northwest of Sami. After an investigation conducted by Yannis Petrohilos and, in 1963, from the Austrian scientists Zolt and Maurin, it was discovered that the waters, which one loses track of in Katavothres, flow into the village of Karavomilos by underground rivers every 15 days. Thus, a small salt-water lake has been created here. This unique phenomenon attracts many tourists to the area.

  

KATAVOTHRES
Katavothres, situated 3 km outside Argostoli in the area of Fanari, constitute a peculiar geological phenomenon. At first it was observed that the water from the sea went into the ground through holes and then it disappeared. After a thorough investigation, initially performed by Ioannis Petrohilos and in 1963 by the Austrian scientists Zolt and Maurin, it was discovered that the water, through underground rivers, flooded in the village of
Karavomilos, in the east, 15 km away and in the spring Fridi at Agia Eyfimia, after approximately 15 days. In this area, in the early 20th century, there was a hydroelectric factory and ice factory, for the exploitation of the underground water.
